122-acre reservoir in Jackson County, Wisconsin. The lake tops out around 4 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Every species below gets its seasonal read from the same numbers driving the chart.
Seventeen Flowage maps at 122 acres behind 2.1 miles of shoreline. Nearly circular (index 1.3), so the story is the bottom, not the bank. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. End to end it runs roughly 0.8 mi, about 0.3 mi across. Jackson County claims this one. Partridge Crop Flowage sits 1 mi northeast — the closest neighbouring chart.
Spring puts yellow perch in skinny water — 1 to 4 ft is the zone. Summer fish stay in 1 to 4 ft, and winter fish hold in 1 to 4 ft. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
